I had a cat that started doing this and I later figured out why. He was an indoor cat but there was a cat who had been walking in my yard and apparently he got the scent of that cat. He started peeing on the floor (not spraying) so I had to barricade him in the kitchen. Then I started taking him outside for a walk around the house with a harness and the behavior stopped. I think that just by walking around outside he was essentially "marking" his territory without spraying or peeing. It worked anyway.

Medical catnip? We call it "kitty crack"

Cat Peeing
 

I also watch Galazy Jackson on the animal planet and he suggested this too...also he always says, food, play and sleep is what they need..LynnDeb

try the vet maybe an infection

I also watch "My Cat From Hell" on Animal Planet -- most episodes are shown on Saturday nights. Fortunately Magic (my original cat) was a champ about using the litter box and Molly (the cat who adopted me 4 weeks ago) has been a champ so far about using the litter box.

During one episode of "My Cat From Hell" a cat was peeing inside the house because the indoor cat saw other cats outside the window, and so was marking inside of the house as his (or her) territory. Could it be that your cat is doing the same thing? I hope you are able to solve your problem soon.

I remember seeing that episode. BTW, it's not my cat that has the problem. Our cats use the toilet, flush when they're done, put the seat back down and then spray with air freshener! :1rotfl:

Happy Employee, you have my sympathy. Most of us can probably put up with aggression, shredded furniture, and the other not-so-pleasant byproducts of our feline friends, but living in a cat pee house seriously tests the limits.

All these suggestions are terrific but you can probably expect to try several things to see what works. Cats are inscrutable! Here's hoping for a favorable result.

This Evening's "My Cat From Hell"
 

This problem was addressed on last evening's program (at 8 PM) on the Animal Planet. I didn't see it, but my sibling did. She said the host brought a vet to the home. The problem was the cat had been declawed, and I think she said the vet stated that this results in a clipping down to the first knuckle.(?) Thus, it hurts for the cat to even walk (let alone use a litter box). My sibling reported that the vet did a procedure using a laser. She said this cured the problem. I don't recall if she said it did so immediately, or if it took a short time for the feet to heal after the procedure.

I wasn't able to scroll back to see what the 8 PM show was titled. But, it will be one of the following two titled shows. I know this because the "My Cat From Hell" shows are repeated again later in the evening, on the same channel. Both of these one hour programs had a segment re: cats urinating other than in the litter box.

1) "Big Bea Ruins Our Social Life" .. Jackson (host) must work his magic on a cat that urinates everywhere; another feline that wrecks two women's love lives.

2) "Bea Hates CeCe" ... A woman and her sweet cat are terrorized by a nasty feline; a Persian pooh-poohs the use of a litter box.

I'm hoping you'll be able to watch both shows on your computer, to see what solutions were offered. I'd hate for you to have to get rid of the cat. GOOD LUCK!
